@kstampo. I checked out the site. I see exactly what you mean. I have had a couple other persons report the same problem. I have tried to test it out and understand it in the past. From what I can tell, the problem is how the text is encoded. It is a multi-byte encoding and that uses combining characters to represent a character with a special accent. So, instead of representing the language specific character with the accent as a single utf-8 encoding, it splits it into 2 characters: an ascii character and the accent character. However, when PHP gets this and tries to display it in the html page, it does not combine it but show one right after the other. I have tried to use the mb functions in php to fix it, but it doesn’t help. I am inclined to think that the issue is not really php or joomla but the file system represents the filenames. Please have a look at this site for a similar explanation of the problem.
Although, I suspect that it is a file system issue, I am open to possible solutions, especially since it would be good for my plugin.
I’m sorry that I don’t have a more definitive answer, but I will keep looking!
